      BSL2 is not an appropriate biosafety level for working with infectious SARS-related coronaviruses. Especially the ones you've already determined can replicate in human cells and use the human ACE2 receptor.

      Some are asking for better regulation of pathogen research regardless of Covid origins. I'm with you, but it seems like it's not moving the leaders who have the authority and power to push for those regulations. Their strategy is MORE pathogen research.https://twitter.com/Ayjchan/status/1369824489505177600 …

      Hoping to press the point here about why it is so important to understand whether the current pandemic arose from the wildlife trade/environmental destruction vs research activities. The pandemic prevention strategies are in complete conflict for each scenario.

      So... in other words, more of the same research (any new regulation?) that didn't help to prevent or find a cure or vaccine to this pandemic, but might have even potentially caused it. Will the funders actually have an excel spreadsheet tracking the pathogen samples this time?

      This situation... Virologists say that virologists are unlikely to have caused the pandemic. Virologists say that more virology (and more funding for virologists) is needed to prevent a future pandemic.

      Oof there are so many logical fallacies in one short thread that it's hurting my head. It's not impossible that it leaked, it is just more probable that it is natural, as most viruses are. So the burden of proof is on those who claim this virus is "special".

      How are you making that calculation? Just baffles me that people confidently make such claims based on little verifiable evidence—even most basic early outbreak data has been withheld, censored and/or is inconsistent and contradictory. We don’t know much is an honest answer.

      I agree we don't know much is the honest answer. This thread is not saying that. Ergo, it's a bad take. And in uncertainty, it is better to go with the more plausible explanation than a wilder one. The calculation comes from statistical probability of evolved viruses vs. leaked.

      You can’t make such a calculation based on what we little know. There’s been no real independent investigation. Databases are missing, most basic requests have been rebuffed and the official claims are contradictory. Makes no sense to be doing “statistics”.

          Agreed: 'Makes no sense to be doing “statistics”.' And yet I built a tool that demonstrates how one can update their zoonotic v lab priors as new evidence comes to light: https://getguesstimate.com/models/18631  (opportunities for biases abound🧐) Welcome to play with values, copy, mod & extend

          Replying to @BlockedVirology @zeynep and

          It is based on Bayes Theorem for updating prior probabilities. (Intuitive youtube background video here on Bayes: https://www.youtube.com/watch?v=HZGCoVF3YvM … ) As each fresh piece of evidence comes to light, the tool updates the probabilities of zoonotic and lab leak simultaneously.
